Question

select the correct answer
which type of exercise contributes most to building strong bones?
a. swimming
b. lifting weights
c. walking briskly
d. jumping rope

Explanation:

Weight - bearing exercises put stress on bones, which stimulates bone - forming cells. Lifting weights is a form of resistance training (a type of weight - bearing exercise). Swimming is a non - weight - bearing exercise as the water supports the body's weight. Walking briskly is a weight - bearing exercise but the impact and stress on bones are relatively less compared to weight - lifting. Jumping rope is a weight - bearing exercise, but the intensity and the way it targets bone density (mainly lower body in a more repetitive, less muscle - mass - engaging way compared to weight - lifting) is not as effective as weight - lifting for overall bone - building (as weight - lifting can target multiple bone - bearing areas with more muscle - bone interaction).

Answer:

B. lifting weights
